fax 01-972-952-9435. AbstractA "typical" North Slope well is a thing of the past. Twenty years ago, a rig would sit on a Prudhoe pad and drill dozens of 10,000 bopd wells. Today, a rig might drill multi-laterals one month, and exploration wells 60 miles from infrastructure the next. Diverse well types and changing economic drivers warranted a new look at North Slope rig designs.In 1997, BP Alaska began researching what the drilling machine of the future should look like. Conceptual drawings were drafted and several new design tenets emerged. First, the rig had to be safer and more automated. Second, it had to reduce well costs. Third, it had to be lighter and smaller. Fourth, it had to be better suited for cross-tundra rig moves.In May 2000, BP chose Phoenix Alaska Technology (PAT) to finalize the design, construct, and operate the rig. In March 2001, PAT began constructing a state-of-the-art, fully automated drilling rig that is expected to commence operations on the North Slope in early 2002. The rig weighs less than half that of a conventional North Slope rig of equivalent horsepower. A single operator controls all drilling, tripping, and horizontal setback operations from a computerized control station.This paper discusses the first four stages of this project: 1) The conceptual design phase by the operator, BP, 2) conceptual design phase by the contractor, PAT, 3) final engineering and specification by PAT and its subcontractors, and 4) rig fabrication. This case study also explores the basis for the design and the features of a light automated drilling system (LADS) that is expected to meet the objectives.

“…In oil drilling industry, the pipe auto-handling device, which is a quite important part to realize pipe auto-delivering during operation, can be hung on the second stage of the K-type derrick to realize pipe grab, move, location and adjustment [4,5]. The ellipsographis used to draw ellipse as a drafting instrument.…”

A design scheme of ellipsograph-mechanism-based pipe auto-handling device (PAD) in continental scientific drilling rig is presented. The working principle of ellipsograph and its characteristics are firstly analyzed to satisfy the requirements of the movement structure of the PAD. Then, the kinematics and dynamics analyses of the structure are conducted respectively to obtain the relationship among each key joints and the relationship between force and its kinematics parameters. Finally, for a certain behavior path, a computation formula of the theoretical consumed energy is developed, and the relationship between energy consumption and the boom length of the structure is acquired. An energy consumption law of the movement structure of PAD under the given condition is obtained. The method presented in this study provides a theoretical basis for the design of ellipsograph-mechanism based PAD, and the energy consumption computation can be applied to many other structures for minimizing their energy and force.

“…With the introduction of computers in drilling machinery, we saw the rush to add them to tasks that mimic manual rigs. 2 As we gradually wrestled with performance improvements, we found ways to apply the systems to multi-tasking, a process aided by computers. To manage all the rig systems and data, we focused on improving the availability of information and ergonomics, but the increasing complexity continued to lack structure.…”

By reminiscing about new drilling rig construction for the last 15 years, this paper proposes a change of thinking in reducing both cost and risk through the application of lessons learned. Every individual who has been involved in building rigs carries their own lessons learned forward, and they naturally apply them to their next construction project. Historically, these collective lessons have not been proactively focused for the good of the industry. Therefore, the intent of this paper is to draw upon the concurrent themes of these lessons learned and, in turn, propose industry-wide solutions when dealing with newrig construction.The group with the broadest exposure to execution challenges, and the subsequent source of the information within this paper, can be found with the suppliers, installers, and integrators of the equipment and controls on new-build rigs. In our most recent construction cycle, the introduction and application of the most successful pastera behaviors has removed considerable risk from the emerging processes. The emerging processes that have been developed are the product of increases in complexity and the subsequent integration challenge that comes from numerous control systems. However, as it is known, these control systems are expected to work as one harmonious drilling machine, and historically this has not been the case! Impressive early results have shown marked improvements with the implementation of complete standard rig designs. These results have reduced the overall risk, and in some cases, they have shown how the innovative utilization of simulators early in the process to try and face construction woes, prior to the actual construction process, can avoid hitting a bottleneck in the process.
